A technical scheme of the invention is: a fungicide for compound oilfield reinjection water is prepared by quaternary phosphonium salt, dibromo nitrilo propionamide, 50% glutaraldehyde solution, and water, wherein the mass ratio of the quaternary phosphonium salt, the dibromo nitrilo propionamide, the 50% glutaraldehyde solution, and the water is 20-30: 10-20: 10-20: 30-60. The quaternary phosphonium salt is one of tetrakis hydroxymethyl phosphonium chloride and tetrakis hydroxymethyl phosphonium sulfate. The present invention provides a highly efficient fungicide for compound oilfield reinjection water.
Description
Technical field
The present invention relates to oil field reinjection water water treatment with medicament, refer to a kind of Compositional type oilfield reinjection water sterilizing agent and preparation method thereof especially.
Background technology
In the secondary oil recovery of oil field, need a large amount of reinjected water, due in reinjected water containing a series of bacterial micro-organism being unfavorable for water flood recovery such as easily cause that metal erosion, formation blockage, chemical agent go bad such as sulfate reducing bacteria (SRB), saprophytic bacteria (TGB) and iron bacteria (IB).Reinjected water contains higher calcium ions and magnesium ions simultaneously, easily produces waterflood-transmission line and stratum serious scale, thus causes waterflood-transmission line and formation blockage.These cause huge economic loss all to oil field production run.Therefore, need before produced-water reinjection, add bactericide and corrosion inhibiting and descaling agent carries out pretreatment.The bactericide that current oil field uses is the medicament continuing to use domestic use of water and industrial circulating water, can be divided into aerobic type bactericide and non-oxygen type bactericide by its sterilization mechanism.Due to oil field environment and the requirement difference to water quality, kind and the harm thereof of bacterium are different, therefore also different to the performance requirement of bactericide.
Bacterium is biological the same with other, also will be subject to the restriction of environmental factor.Can according to affect bacterial growth because usually selecting sterilization algae removal medicament: generally consider from following several respects: the respiration 1. hindering thalline; 2. the synthesis of Profilin matter, or destroy the moisture film of protein, or in and the electronics of protein, make protein precipitation and lose activity; 3. destroy thalline internal and external environment balance, make its dehydration withered and dead, or water-filling expands and dies; 4. hinder the synthesis of nucleic acid, lose and change the activity of its nucleic acid.In addition, also will consider the factors such as environmental protection, some medicament disinfectings are very capable, but can not biological degradation, and some medicaments can kill the nutrient solution of this bacterium but other bacterium, and these all can not be used for oil field sterilization.In addition, the impurity in the geological condition in oil field and water all can affect the drug effect of bactericide.Current effect good oil field bactericide is based on surfactant-based, but due to a large amount of foam can be produced when throwing in surfactant series bactericidal agent, simultaneously surfactant series bactericidal agent can and water in organic matter and other impurity complexing and lose germicidal efficiency, therefore often to add defoamer when using surfactant series bactericidal agent, must clean oil well simultaneously, operational administrative that anti-row, acidifying etc. are strict.The vitality of bacterium is extremely strong, and any one bactericide length service time all can make bacterial resistance occurred, causes the problems such as the germicidal efficiency of bactericide declines, dose increase, therefore, needs constantly to develop new oil field bactericide.
Summary of the invention
The present invention is directed to above-mentioned Problems existing and deficiency, provide a kind of Compositional type oilfield reinjection water sterilizing agent and preparation method thereof.
Technical scheme of the present invention is: a kind of Compositional type oilfield reinjection water sterilizing agent, it is characterized in that, by quaternary alkylphosphonium salt, di-bromonitrilopropiona,ide, 50% glutaraldehyde water solution and pure water combine, wherein, quaternary alkylphosphonium salt, di-bromonitrilopropiona,ide, the glutaraldehyde water solution of 50%, the mass ratio of pure water are 20 ~ 30:10 ~ 20:10 ~ 20:30 ~ 60.Described quaternary alkylphosphonium salt is the one in THPC and tetrakis hydroxymetyl phosphonium sulfuric.
The preferred technical scheme of the present invention, is characterized in that, in bactericide, quaternary alkylphosphonium salt, di-bromonitrilopropiona,ide, the glutaraldehyde water solution of 50%, the mass ratio of pure water are 22 ~ 28:10 ~ 20:10 ~ 20:30 ~ 60, and this bactericide is concentrated type liquid preparation.
In technical solution of the present invention, THPC is the aqueous solution, is the fire retardant of conventional cotton textiles, polyester-cotton fabric.Tetrakis hydroxymetyl phosphonium sulfuric is the aqueous solution, is commonly used for quaternary alkylphosphonium salt bactericide, is also the fire retardant of conventional cotton textiles, polyester-cotton fabric.
Di-bromonitrilopropiona,ide (another name DBNPA, is called for short DBNPA) is a kind of new and effective Biocidal algae-killing agent and water treatment agent.This material has high-efficiency broad spectrum, the easily advantage such as degraded, noresidue residual hazard, environmentally safe, meanwhile, has sterilization algae removal concurrently, kills the function of the potion multiple-effect such as sticky removing dirt and inhibition.As water treatment agent and the Biocidal algae-killing agent of high-efficiency low-toxicity, environment-friendly type, DBNPA has broad application prospects and Development volue, is more and more subject to people and pays close attention to.Because this product bactericidal property is good, free from environmental pollution, be used widely in developed country, but domestic its relevant research report rarely seen.
Glutaraldehyde water solution has wide spectrum, efficient and quick-acting bactericidal actions.Good killing action is all had to bacterial propagule, gemma, virus, tubercle bacillus and fungi etc.And low toxicity, little to metal protection, little by organic substance influence, good stability.
The invention provides a kind of preparation method of Compositional type oilfield reinjection water sterilizing agent, by four kinds of materials according to certain mass ratio to put into successively in stirred vessel stirring and dissolving product of the present invention.This bactericide is concentrated type liquid preparation, can dilute 40 ~ 50 times of uses.In the present invention, four kinds of materials press certain mass than composite use, bactericidal effect is obviously better than wherein any one material and is used alone, to sulfate reducing bacteria (SRB), saprophytic bacteria (TGB) and iron bacteria etc., all there is good killing effect, and foam is few, the domestic existing oilfield reinjection water sterilizing agent usage amount of amount ratio is low by 20 ~ 30%, can save the reagent cost of oil field reinjection water.
Oilfield reinjection water sterilizing agent in the present invention is stablized in high rigidity, high alkalinity, the effect of high-temperature Water Under solution, all there is good bactericidal action to fungi, slime forming bacteria, particularly sulfate reducing bacteria, iron bacteria, saprophytic bacteria, the field such as oil field reinjection water and conventional chilling water treatment can be widely used in.
